1.0.0[][src]Function std::env::temp_dir

pub fn temp_dir() -> PathBuf

Returns the path of a temporary directory.

Unix

Returns the value of the TMPDIR environment variable if it is set, otherwise for non-Android it returns /tmp. If Android, since there is no global temporary folder (it is usually allocated per-app), it returns /data/local/tmp.

Windows

Returns the value of, in order, the TMP, TEMP, USERPROFILE environment variable if any are set and not the empty string. Otherwise, temp_dir returns the path of the Windows directory. This behavior is identical to that of GetTempPath, which this function uses internally.
